I need help the velo code about my team section

If you Go in the last section you can see team section when you click the plus icon show the details and when you click minus icon close the details.

This page name is New page. I use this code.

$w.onReady(function () {

    // Plus Icon click → show text + show minus + hide plus
    $w("#plusIcon").onClick(() => {
        $w("#hiddenText").expand(); 
        $w("#plusIcon").hide();
        $w("#minusIcon").show();
    });

    // Minus Icon click → hide text + show plus + hide minus
    $w("#minusIcon").onClick(() => {
        $w("#hiddenText").collapse(); 
        $w("#minusIcon").hide();
        $w("#plusIcon").show();
    });

});

Now if you go in the about page last section here is the team section but the code is not working here

About page I use repeater. But it is not working. Which code is working in the repeater.

This page name is New page. I use this code.

$w.onReady(function () {
// Plus Icon click → show text + show minus + hide plus
$w("#plusIcon").onClick(() => {
    $w("#hiddenText").expand(); 
    $w("#plusIcon").hide();
    $w("#minusIcon").show();
});

// Minus Icon click → hide text + show plus + hide minus
$w("#minusIcon").onClick(() => {
    $w("#hiddenText").collapse(); 
    $w("#minusIcon").hide();
    $w("#plusIcon").show();
});

$w("#repeater6").onItemReady(($item) => {

    // PLUS CLICK → text show + minus show + plus hide
    $item("#plusIcon1").onClick(() => {
        $item("#hiddenText1").expand();
        $item("#plusIcon1").hide();
        $item("#minusIcon1").show();
    });

    // MINUS CLICK → text hide + plus show + minus hide
    $item("#minusIcon1").onClick(() => {
        $item("#hiddenText1").collapse();
        $item("#minusIcon1").hide();
        $item("#plusIcon1").show();
    });

});
